TIMOTHY L. OARLEY, OF SYRACUSE, NEW YORK, ASSIGNOR OF ONE-HALF TO LOUIS F. POWELL, OF SAME PLACE.

SAW-FRAME FOR CIRCULAR-SAW MILLS.

SPECIFICATION forming part of Letters Patent No. 290,174, dated December 11, 1883.

Application filed June 30, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, TIMOTHY L. CARLEY, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements inSaw-Mills, of which the following, taken in connection with the accompanying drawing, is a full, clear, and exact description. 4

This invention relates to the mill-frame which supports the two sawarbors of a double circular-saw mill. 1

The object of the invention is to provide simple, convenient, and reliable means for simultaneously adjusting two arbors, so as to I 5 give the two saws more or less lead, and at the same time maintain them in parallelism.

The annexed drawing represents an isometric view of my invention, in which A denotes the stationary bed, which is firmly sec'uredin its position by any suitable and wellknown means. Upon this bed I mount, movably, a horizontal frame or yoke, B, which reaches across the bed and. is provided with bearings a a, for the arbor b of the main or lower saw,

S. This yoke I secure'adjustably in its posi tion by means of set-screws d d. which either work in lugsl Z, fixed to the bed, and bear against the sides of the yoke. or, conversely, work in lugs Z Z on theyoke and abut against gothe lugs H on the bed. By turning the aforesaid set-screws the yoke B, with the arbor I, can be shifted to'give the saw S more or less lead, as may be required.

It is obvious that wedges or cams, or eccen- 5 tries or other analogous devices can be employed in lieu of the set-screws d d, and I therefore do not limit myself in that respect. The yoke can be further secured in its required position by bolts 0 0, passing through slotss s 40 in the yoke and into the bed A, as shown.

P P are pedestals or standards. which are rigidly attached to or integral with the yoke B, and are therefore caused to move synchronously with the adjustment of the yoke, the pedestals being provided with the usual bearings, e e, for the arborf of the top saw, S, and thus causing the latter to be adjusted simultaneously with the lower saw, and maintained in parallelism with the same.

Aside from the already-recited advantages derived from my invention, it will be observed that I dispense with the extra longitudinal sill, which heretofore was used between the two outer beams of the bed A for supporting the pedestal P.

Having described my invention,what I claim as new, and desire to secure by Letters Patent, 1s-

1. In combination with the stationary bed,

a yoke mounted movably on said bed and provided with bearings for the arbor of the lower saw, pedestals rigidly attached to the yoke and provided with bearings for the arbor of the upper saw, and an adjustable fastening for securing the yoke in its position on the bed, substantially as shown and set forth.

2. In combination with the stationary bed,

a yoke mounted movably thereon and provided with bearings for the arbor of thelower saw, pedestals made integral with the yoke and provided with bearings for the arbor of the u er saw, lugs or shoulders fixed to the bed, and setsorews, or their equivalent, arranged between said lugs and yoke, substantially as described and shown, for the purpose specified.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse,in the county of Onondaga, in the State of New York, this 22d day of June, 1883.
